Besides the sun, what is the constellation of the nearest star?

Besides the sun, the nearest star is proxima centauri.

Proxima centauri was discovered by astronomer Robert innis in 19 15. It is the closest star to the earth except the sun, only 4.2 light years away, about 40 trillion kilometers away. It is located in Centauri, because it is the closest star to the earth except the sun, so it is named proxima centauri.

Proxima centauri belongs to a trinity system, which contains three stars: Alpha Centauri A, B and C, among which Alpha Centauri C is what we usually call proxima centauri. Proxima centauri is a red dwarf star, orbiting two other stars at a long distance.

The distance from proxima centauri to the earth is ten thousand years.

Ten thousand light years is the astronomical unit of distance, which refers to the distance traveled by light in one year, which is about 9,460.5 billion kilometers. Besides the sun, the nearest planet is Venus and the farthest planet is Neptune.

Venus is in Earth's orbit. Venus is at perihelion, the earth is at perihelion, and when the earth, Venus and the sun are in a straight line, Venus is closest to the earth.

Venus is 10894 million kilometers away from the sun at perihelion, and the earth is 14765438+ 10,000 kilometers away from the sun at perihelion. If it is subtracted, the nearest distance from Venus to the Earth is equal to 38160,000 km.
